The hydrogen production that would be required to fully replace carbon fuels in aviation is monumental: the near future of aviation is either degrowth, or climate change denial with a bit of hydrogen on top. I'm afraid we are heading for the second option.

This is my worst nightmare as a traveler. It would mean traveling would be rich people only and us 99.9% normies would pick one country to go every decade and just watch the rest on YT like during Covid.

This can either be regulated by the prices (only the rich can afford) or by the quantities (everyone is allowed a limited amount of travels in their life). I wish for the latter, but wouldn't bet much on it; having either would already be a big step. As for travelling, this could be the occasion of a big revisiting of what doing tourism means: it would still be possible to change continent once in a while, just not for the weekend. Trains can get your pretty far in Eurasia. Boats also need a fuel revolution but will hopefully get there.

Not to mention airport infrastructure is not setup for hydrogen fuel. Not saying they couldn't do it but it would probably cost a lot of money.
